if you are not able. to obtain Pullets for him, use Black Breasted Red hens.
That would be a very good option, you may also consider Ginger Red hens.. Male color will be less affected in the F1. all the Black tailed red I am aware of started from hatchery and still need a great deal of improvement in size, type and color characteristics. A very well typed BB red hen from a strong hen line breeding but maintaining very good feather width would be the best first step. keep pullets from teh F1s to breed back to the cock then a cockrell from that to breed back to the f1 hens, should give you strong start.
